五、治疗及抢救国内的肺心病主要继发于慢性阻塞性肺部疾病,其病理生理主要是呼吸功能不全导致缺氧引起肺动脉高压,最后引起肺心病。肺心病急性发作的诱因多数由于呼吸道感染。所以治疗主要是:(1)控制感染;(2)改善通气,提高PaO_2,降低PaCO_2;(3)改善缺氧,适当吸氧治疗;(4)在呼吸衰竭时,肺水增加,故利尿剂的应用有其特殊价值。一般肺心病急性发作地患者,只要积极有效地控制感染、改善通气、适当地吸氧、给予利尿剂,心肺功能不全症状就能得到控制。只在少数重症心力衰竭患者需考虑应用强心甙及血管扩张剂。现将治疗措施分项讨论如下:
Fifth, the treatment and rescue Pulmonary heart disease in the country mainly secondary to chronic obstructive pulmonary disease, the main pathophysiology is caused by respiratory insufficiency caused by hypoxia pulmonary hypertension, and finally cause pulmonary heart disease. Most of the causes of acute pulmonary heart disease due to respiratory infections. Therefore, the treatment is mainly: (1) control of infection; (2) to improve ventilation, increase PaO_2, lower PaCO_2; (3) to improve hypoxia, oxygen therapy appropriate; (4) respiratory failure, pulmonary edema, The application has its special value. Patients with acute onset of pulmonary heart disease, as long as the positive and effective control of infection, improve ventilation, appropriate oxygen, given diuretics, cardiopulmonary insufficiency symptoms can be controlled. Only in a few patients with severe heart failure need to consider the application of cardiac glycosides and vasodilators. The treatment measures are now discussed as follows:
